    • createItem

      protected Item createItem(SessionContext ctx, ComposedType type, Item.ItemAttributeMap allAttributes) throws JaloBusinessException
      Description copied from class: Item
      Has to be implemented for each concrete subtype of item. This method is responsible for creating a new item instance ( by calling managers, ejb homes, etc. ) during ComposedType.newInstance(Map).

      In case this method uses any of the attribute values during creation it is required to override Item.getNonInitialAttributes(SessionContext, ItemAttributeMap) too.
      Sn example:

      
       public static final String MY_ATTRIBUTE = "someAttribute"; ... protected Item createItem(SessionContext
       ctx, ComposedType type, Map allAttributes ) throws JaloBusinessException { MyManager man = ... return
       man.createMyItem( (String)allAttributes.get(MY_ATTRIBUTE) );
       // here MY_ATTRIBUTE is used for creation, so it must not be set again } protected Map getNonInitialAttributes(
       SessionContext ctx, Map allAttributes ) { // let superclass remove its own initial attributes Map ret =
       super.getNonInitialAttributes( ctx, allAttributes );
       // remove MY_ATTRIBUTE from all attributes since if has already been set ret.remove(MY_ATTRIBUTE); return ret; }
      
       
      Overrides:
      createItem in class GenericItem
      Parameters:
      ctx - the current session context which this item is created within
      type - the actual item type ( since subtypes may not provide a own jalo class this may be different from the type which this method was implemented for )
      Returns:
      the new item instance
      Throws:
      JaloBusinessException - indicates an error during creation - any changes will be rollbacked
    • toString

      public String toString()
      Description copied from class: Item
      Returns the String representation of this item. This is by default the representation of the primary key of this item.
      Overrides:
      toString in class Item
      Returns:
      the String representation of this item.
    • getConvertibleUnits

      @Deprecated(since="ages", forRemoval=false) public Set<ClassificationAttributeUnit> getConvertibleUnits(SessionContext ctx)
      Deprecated.
      since ages - use classificationSystemService.getConvertibleUnits(attributeUnit)
      Shows all other unites of the same type and system version. Usually these units are convertible using their conversion factor attribute.
      Specified by:
      getConvertibleUnits in class GeneratedClassificationAttributeUnit
      Returns:
      the convertibleUnits - Convertible units
    • convertTo

      public double convertTo(double doubleValue, ClassificationAttributeUnit otherUnit)
